LEVER MECHANISM.

Specification of Letters Patent.

A Application filed December 20, 1909. Serial No. 584,066,

1 T0 dll'whom it may concern:

'Be it known that I, JAMES l )muo'rn, a citizen of the United States,and a resident ofPm-tland, in the county of Multnoniah ut""aiid Stateof()regon, have invented certain J-new and useful Improvements in LeverMeehanism, of which the following is z 'specificat ion.

My inventionis an improvement in lever o' mechanism, and consists incertain novel j constructions, and combinations of parts h'ereinat'terdescribed and claimed.

, v {The object of the invention is to provide a simple lever mechanismfor operating the 'ispwinding gear of a hoisting engine, or simi- "lardevices, wherein both the Winding drum andthe tripping drum are operatedby a I single lever, "thusleaving one hand of the engineer free forother purposes, as, for in i- 0- 'stanee. to handle the throttle.

, 1 Referring to the drawings forming a part EhereofF-Fi ure 1 is a sideview of the improvement. Fig. 2 is a plan view partly insection. Fig. 3is a detail perspective view. of a portion of the operating mechanism,and Fig. 4 is-a side view of the same.

In the present embodiment of the invention, the hoisting drum 1 and thetripping drum 2are mounted on a single shaft 3,

-BOWvhiehis journaled in bearings 3, on a frame c'onsisting'of sideplates t and 5, which are t j -secured to the floor or other supports bybolts 6.

' 'Thedrums 1 and 2 are loosely journaled on'the shaft, and each drum isprovided, on

{its inner end, with an annular marginal {flange 7 having a collar 8secured thereto,

, the lnner surface of which'is conical, as

shown. The collar is of material having a and forms one portion of afriction clutch.

A disk 9 is secured on the shaft between the drums and is provided withan annular -series of crown teeth 10, and on each sideof the teeth witha conical projection 11 adapted to engage the inner surface of thecollar '8," when the adjacent drum is moved toward 'fthe disk, andclutch the said drum to the -disk and to the shaft.

#- MA drive shaft 12 is jourrialed in front of f the shaft 3 andparallel therewith in bean V -&ings- 13 on brackets 13*, and. the shaftis 1 provided with a pinion 14 meshing with the orownteeth of the disk,A disk 15,'pro- W5 -videdwith a wrist pin 16, is secured on ahle in eachguideway. A cylinder21 is supported on eachhase"19,'and the piston rod22 of the cylinder is 'eonneeted'with one end of the adjacent hlock,andthe'block is connected by a link 23 with the Wrist pin 16 of theadjacent disk.

A counter oroperating sh 'aft24 is journaled in bearings25 on thesideplates, in front of the drive shaft, and'an arm 26 is secured to oneendof the shaft outside of the hearings. Ablock 27 is a-djustably securedto the other end by a set screw 28, and an arm 29, is seci'i'reddiagonally to the outer face of the block byholts'or rivets'30.

The drums'nre; movahle longitudinally of v the shaft 310 connectillelllltrflhll diseonneet them from the disk, and are operated by meansof the usual screws 43 and43", the screw 43 o 'ierating the hoistingrope drum, and the screw43 the tripping rope drum. A lever3l isiprovidedatone end with a grip 32, and at t ie other "with a split hearing 33which engages the outer end of the screw 43, and a bolt34; is providedfor clamping the sections of the bearing on the screw. The lever isfurther secured by a key 35. V v

Asuhstantially triangular plate 36 is pro .vided at itsphase end[Withopenings 37 for receiving bolts 38, whereby it may besecured totheilever, and the apex end of the plate is provided ivith a lateralflange 39 through whichis threaded a, set screw 40. p A link 4].isvpivoted by onefend, as at 42, to the I plate near the apexend," andthe opposite nd of the link is pivoted to the outer end of thear1n29,before. inentioned.

The screw 43*has secured to the outer end thereof an arm 44, which isconnected by, a.

link'45 with the arm 26 on the shaft. 24. The cylinders 21 are suppliedwith motive fluid th-rough the pipes 46-fro'm'any' suitable son'rce,andare'ojf any usual'or desired constructio r a In operatiomthemotive'fiu'id is admitted to the cylinders, and the' blocks or crossheads 20 are reciprocated in the ideways, thus rotatin the driving shag12, and through the mtermeshing-of the pinion and crown teeth, the diskis also rotated. The hoisting rope and'thetripping'rope are 11 connectedwith their respective drums, so

- that when the drums rotate, they will be 4 wound or unwound inaccordance with the di r ction of rotation. i

t will be observed that the connection between the shaft 24 and thescrews 43 and 43 is such that when the said shaft is.oscillated towardthe left in Fig. 1, the screw 43 is turned in one direction, while thescrew 43 is turned in the other, so that when the said shaft isoscillated in either direction, one screw will be operated to con'-'nect its drum with the disk, while the other will be operated todisconnect its drulnfrom the disk.

When the lever 31 is moved into the po-" sition shown infull lines inFig.1,the hoist-- :for simultaneously moving the drums in the samedirection, so that when one is engaged with the driving means, the otherwill be disengaged therefrom.

I claim:-- a
